The user terminal according to an exemplary embodiment may be an MP3 player, smart glasses, a virtual reality device, etc. Each user 13 has their own user terminal 12. Each user 13 and the user terminal 12 may be located around the display device 11. Each user 13 may control their own user terminal 12 while watching the display device 11. Each user 13 may cause the display device 11 to provide the content he / she desires through his / her own user terminal 12.

[0043] The display device 11 may provide the content selected by each user according to a request from each user 13 using the user terminal 12. The type of content provided by the display device 11 is not limited, but the content may include, for example, music, moving images, photos, web page information, etc. The users 13 may share the content they have selected using their own user terminals 12 and the display device 11. For example, multiple users 13 who have returned from a trip may use the display device 11 to share photos taken at the same location and at the same time. According to an exemplary embodiment, the display device 11 and the user terminal 12 may allow multiple users 13 to share their content with each other at the same location, thereby having a new and worthwhile content sharing activity experience.

[0044] According to an exemplary embodiment, the content sharing activity may include the following matters. That is, each user 13 may select the content he / she likes as the content to be shared. For example, each user 13 may select the content created by herself through the user terminal 12, the content filtered based on his / her taste, etc. as the content to be shared. The users 13 may respectively manipulate their own user terminals 12 to express their preferences, tastes, opinions, etc. on the display device 11 while sharing the content.

[0045] Therefore, through the display device 11 and the user terminal 12 according to an exemplary embodiment, multiple users 13 in the same location may share content with each other about music, moving images, photos, etc. that reflect their interests, tastes, etc. through the user terminal 12 and the display device 11, and may also talk to each other while watching the screen for sharing the content, thereby obtaining a more worthwhile experience, wherein the user device 12 may be respectively manipulated by multiple users 13, and the display device 11 may be watched by multiple users 13 at the same time.

[0046] Figure 2It is a block diagram of a display device 11 according to an exemplary embodiment. The display device 11 may include an image processor 21, a display 22, a first communicator 23 (e.g., a communication device, interface, and / or transceiver), and a controller 24 (e.g., a processor and / or microprocessor). The image processor 21 performs image processing to display a user interface (UI) for sharing content and / or an image of the content. The display 22 displays the UI and / or the image processed by the image processor 21. The first communicator 23 performs communication with the user terminal 12. The controller 24 performs control of the display device 11. The controller 24 performs control in response to a request from each user 13 received from the user terminal 12, such that each user 13 can perform a content sharing activity.

[0047] Figure 3 It is a block diagram of a user terminal 12 according to an exemplary embodiment. The user terminal 12 includes a display 31, a user input device 32, a communicator 33 (e.g., a communication device, interface, and / or transceiver), and a controller 34 (e.g., a processor and / or microprocessor). The user terminal 12 may further include a storage device or storage unit 35. The display 31 displays a UI for sharing content. The user input device 32 receives a user input for sharing content. There is no limitation on the user input device 32. For example, the user input device 32 may include a touch screen for sensing a touch input of a user on the display 31. The communicator 33 communicates with the first communicator 23 of the display device 11. The controller 34 performs control of the user terminal 12. The controller 34 controls the display 31 to display a UI for sharing content and controls the communicator 33 to send the user input received through the user input device 32 to the display device 11, such that the user 13 can perform a content sharing activity.

[0048] There is no limitation on the communication method between the first communicator 23 of the display device and the communicator 33 of the user terminal 12. For example, the communication method may include wireless fidelity (Wi-Fi), Bluetooth, etc. At least one of the controller 24 of the display device 11 and the controller 34 of the user terminal 12 may include a control program, a non-volatile memory in which the control program is installed, a volatile memory that loads at least a part of the installed control program, and at least one microprocessor for executing the loaded control program. The control program may include at least one of the following: basic input / output system (BIOS), device driver, operating system, firmware, platform, and application program. The application program may be pre-installed or stored in the display device 11 or the user terminal 12 during the manufacture of the display device 11 or the user terminal 12, or the application program may be installed in the display device 11 or the user terminal 12 based on the received data by receiving the data of the application program from the outside when using the data of the application program in the future. For example, the data of the application program may be downloaded from an external server such as an application market to the display device 11 or the user terminal 12.

[0049] Figure 4 Shows the operation between the display device 11 and the user terminal 12 according to an exemplary embodiment. Figure 4 The first user terminal 41 and the second user terminal 42 shown in Figures 1 to 3 refer to two user terminals 12 among the plurality of user terminals 12 shown in. For ease of description, Figure 4 only two user terminals 12 among the plurality of user terminals 12 are shown as an example. According to an exemplary embodiment, three or more user terminals are also possible. First, the first user terminal 41 connects to the display device 11 and starts communicating with the display device 11 (S41). Either the first user terminal 41 or the display device 11 may initiate the communication between the first user terminal 41 and the display device 11.

[0050] If the first user terminal 41 initiates the communication, the first user terminal 41 may receive, for example, a user input for starting a content sharing activity from the user 13 through a UI displayed on the display 31. The first user terminal 41 searches for connectable devices around the first user terminal 41 based on the user input for starting the content sharing activity through the UI. If the display device 11 is found to be a connectable device, the first user terminal 41 may connect to the found display device 11 and communicate with it. In this case, when the display device 11 receives a request to search for connectable devices from the first user terminal 41, the display device 11 may connect to the first user terminal 41.

[0051] Specifically, the first user terminal 41 may determine whether to connect to the found display device 11 and communicate with it based on information related to the identification (ID) of the display device 11 (e.g., device ID). In this case, if the display device 11 receives a request to search for devices from the first user terminal 41, the display device 11 may send its own ID information to the first user terminal 41. The first user terminal 41 may also include a storage device 35 for pre-storing the ID information of the display device to be connected for communication, and compare the ID information of the display device stored in the storage device 35 with the ID information received from the found display device 11, thereby determining whether to connect to the display device 11 and communicate with it.

[0052] According to an exemplary embodiment, the first user terminal 41 may determine whether to connect to the found display device 11 and communicate with the display device 11 according to a user input. Specifically, the first user terminal 41 displays information related to the found display device 11 (e.g., device name, device description, etc.) and a message asking whether to connect to the display device 11 on the display 31, and determines whether to connect to the display device 11 and communicate with the display device 11 according to the user input received through the user input device 32. The first user terminal 41 may use near field communication (NFC) with the display device 11 or the remote controller (described later) of the display device 11 to connect to the display device 11 by touching.

[0053] On the other hand, the display device 11 may guide the communication between the first user terminal 41 and the display device 11. The communication guided by the display device 11 may also be implemented in the same way as the above case where the first user terminal 41 guides the communication. In this case, the display device 11 may also include a user input device 25 (see Figure 2 ) for receiving a user input for starting a content sharing activity. The user input device 25 of the display device 11 may include: a panel input unit provided in the main body of the display device 11 and directly receiving a user input, and / or a remote control signal receiver for receiving a remote control signal corresponding to the user input from a remote controller for receiving a user input. The display device 11 may also include a storage device or storage unit 26 (see Figure 2 ) for pre-storing the ID information of the user terminal to be connected for communication.

[0054] Refer again to Figure 4, the second user terminal 42 is connected to and communicates with the display device 11 (S42). The communication between the second user terminal 42 and the display device 11 can be implemented in the same way as the above-mentioned communication between the first user terminal 41 and the display device 11. Alternatively, the second user terminal 42 receives information about the connection to the display device 11 from the first user terminal 41 and thus connects to the display device 11 based on the received connection information. Alternatively, the second user terminal 42 can provide information about the connection to the second user terminal 42 to the first user terminal 41 and thus allow the first user terminal 41 to send the connection information to the display device 11, thereby allowing the display device 11 to connect to the second user terminal 42.

[0055] Alternatively, a user 13 can use two or more user terminals 12. For example, a user 13 can use his / her own smart phone and smart watch as the user terminals 12. In this case, the smart phone among the user terminals 12 can be used to connect to the display device 11 in the name of a certain user, and then the smart watch among the user terminals 12 can be used to connect to the display device 11 in the name of the same user as above. The smart watch user terminal 12 can connect to the smart phone user terminal 12 using a communication method such as Bluetooth, share information with the smart phone user terminal 12, and connect to the display device 11 using Wi-Fi. If a user uses two or more user terminals 12, the display device 11 can display the user and content control status for two or more user terminals 12, or can display the content control status differently according to the user terminals 12.

[0056] Next, the first user terminal 41 selects the content to be shared (S43). The first user terminal 41 displays a UI on the display 31 that allows the user 13 to select the desired content.

[0057] Figure 5 An example of the UI displayed on the user terminal 41 according to an exemplary embodiment is shown. Figure 5 The UI 51 shown in includes a first area 52 and a second area 53. The first area 52 shows one or more items 54 corresponding to each piece of content that can be selected as the content to be shared, and the second area 53 shows an item 55 corresponding to the content selected as the content to be shared. The display of the item 54 and the item 55 can include displaying at least one of information related to the corresponding content, such as a thumbnail image, name, description, etc. of the content. As Figure 5 shown, the item 54 can be displayed as an icon 46 and a corresponding content title 48.

[0058] User 13 can input by touching the first area 52 to search for content to be shared, which can be stored in a storage device, for example. For example, the first user terminal 41 can have a first search function that can be executed via a touch input received through the UI displayed on the first area 52. For example, when the user makes an input 57 of swiping up and down on the first area 52, the first user terminal 41 moves the item 54 of the content shown on the first area 52 up and down, and thus items 54 corresponding to content not shown on the first area 52 appear additionally.

[0059] User 13 can move the content desired to be shared among the multiple pieces of content indicated by the items 54 shown on the first area 52 to the second area 53. For example, if user 13 makes an input 56 of dragging the item 54 of specific content from the first area 52 to the second area 53 on the icon 46 or the corresponding content title 48, the first user terminal 41 can move the item 54 of the corresponding content to the second area 53. Then, the first user terminal 41 displays the item 55 of the content corresponding to the moved item 54 to appear additionally on the second area 53. Alternatively, the user input device 32 of the first user terminal 41 can sense the intensity (pressure) of the touch input on the display 31 within a predetermined range, and when the item 54 corresponding to the content is touched and held and pressed with an intensity stronger than a predetermined level, the first user terminal 41 displays the item 54 of the content to be moved to the second area 53. The first user terminal 41 can also include a sensor 36 for sensing the movement or tilt of the first user terminal 41 (see Figure 3 ), and when the first user terminal 41 moves or tilts in a preset pattern while the user 13 touches and holds the item 54 of the content, the item 54 of the content to be moved to the second area 53 is displayed.

[0060] According to an exemplary embodiment, if user 13 moves the item 54 of the content from the first area 52 to the second area 53, the first user terminal 41 can determine that the corresponding content is selected for sharing. In this case, in response to adding the item 55 of the new content to the second area 53, the first user terminal 41 can display the item 55 of the content moving in the direction 59 toward the edge area of the UI 51. At this time, if the item 55 of the content reaches the top of the second area 53, the item 55 disappears from the second area 53.

[0061] According to an exemplary embodiment, if there is an input from user 13 after item 55 of new content is added to the second area 53, the first user terminal 41 may determine that the content corresponding to item 55 displayed on the second area 53 is selected for sharing. For example, if the user makes an input that causes the first user terminal 41 to tilt towards the display device 11 (i.e., in the upward direction 591), the first user terminal 41 may determine that the user selects the content of the second area 53 for sharing. As the first user terminal 41 tilts in the upward direction 591, the first user terminal 41 may display that item 55 of the content shown in the second area 53 moves in the upward direction 59. Item 55 of the content that reaches the top of the second area 53 disappears from the second area 53. Therefore, the user can see a visual effect as if the content to be shared is moved or poured out from the first user terminal 41 to the display device 11.

[0062] Referring again Figure 4 , if the content to be shared is selected, the first user terminal 41 sends information related to the selected content to the display device 11 (S44). Similarly, the second user terminal 42 selects the content to be shared according to the user input (S45), and sends information related to the selected content to the display device 11 (S46).

[0063] The display device 11 may display the content to be shared based on the information related to the content received from the first user terminal 41 and the second user terminal 42 (S47). The display device 11 may display the shared content according to each user 13.

[0064] Figure 6 An example of a UI displayed on the display device 11 according to an exemplary embodiment is shown. Figure 6 The UI 61 shown in may include one or more items 62 showing the users of the shared content and one or more items 63 showing the shared content. Item 62 showing user 13 who shares content with each other refers to user 13 of the first user terminal 41 and the second user terminal 42 currently connected to the display device 11. Item 62 showing user 13 who shares content with each other may distinguish user 13 by color, name, ID, etc., for example. When the first user terminal 41 or the second user terminal 42 is connected to the display device 11, the display device 11 may assign different colors to user 13 of the connected first user terminal 41 and the connected second user terminal 42. The display device 11 may send information related to the colors respectively assigned to user 13 to the first user terminal 41 or the second user terminal 42 of the corresponding user 13.

[0065] When information related to the shared content is received from the first user terminal 41 and / or the second user terminal 42, the display device 11 may display the item 63 of the shared content (S44, S46). The display device 11 may display the item 63 of the shared content on the UI 61 as if it is moving in a predetermined direction. For example, the item 63 of the shared content may appear on the UI 61 as if it is moving from right to left or from left to right. The display device 11 may display the item 63 of the shared content entering the UI 61 as if it is descending from the top of the UI 61 or ascending from the bottom. Thus, a more emphasized visual effect is given as if the content is being poured from the first user terminal 41 and / or the second user terminal 42 to the display device 11.

[0066] The item 63 showing the shared content may include a thumbnail image, name, description, etc. of the shared content. The item 63 showing the shared content may be distinguished according to the user 13 by the color assigned to the corresponding content by the user 13. Thus, the user 13 can easily identify which user 13 has shared the content through his / her own terminal based on the color of the item of the shared content displayed on the display device 11.

[0067] Each user 13 may use his / her own first user terminal 41 or second user terminal 42 to control the shared content displayed on the display device 11. The operations of the first user terminal 41 and the second user terminal 42 may be similar to each other. For ease of description, the operation of the first user terminal 41 will be representatively described.

[0068] Figure 7 An example of a UI displayed on the first user terminal 41 according to an exemplary embodiment is shown. Figure 7 The UI 71 shown in may include: an item 72 for sorting the shared content displayed on the display device 11, an item 73 for navigating the shared content, an item 74 for starting the reproduction of the shared content, an item 75 for skipping to the next shared content, an item 76 for voting on the shared content, and an item 77 for controlling the volume of the shared content being reproduced. According to an exemplary embodiment, the first user terminal 41 may display the UI 71 in the color assigned to the corresponding user 13 based on the information received from the display device 11. Thus, the user 13 can easily know the color assigned to him / her.

[0069] The user 13 selects one item from the plurality of items 72 to 77 of the UI 71 and thus controls the reproduction of the shared content displayed on the display device 11 (see Figure 4(in S48 and S49 in it). If a user input such as a touch on the UI 71 selects an item from among a plurality of items 72 to 77 on the UI 71, the first user terminal 41 sends reproduction control information corresponding to the selected item (one of the items 72 to 77) to the display device 11 (see Figure 4 (in S491 and S492 in it). The display device 11 displays the reproduction control state of the shared content displayed thereon based on the reproduction control information received from the first user terminal 41 (see Figure 4 S493). The display device 11 can distinguishably display the reproduction control state of the shared content for the user 13.

[0070] Specifically, if an item 72 for sorting the shared content is selected on the UI 71 shown in Figure 7 the first user terminal 41 can display a UI 81 that includes menu items 82 showing sortable categories, as Figure 8 shown. For example, the sortable categories of the menu items 82 can include the type of content, user, time, vote in favor, vote against, etc. The user 13 can select a category from the sortable categories of the menu items 82, thereby sorting the shared content displayed on the display device 11.

[0071] Referring again to Figure 6 the display device 11 can sort and display the items 63 of the shared content according to the category selected in the menu items 82 of the first user terminal 41. For example, if the category of type or user is selected, the display device 11 can display only the items 63 of the shared content corresponding to the selected type or user. If the category of time is selected, the display device 11 can sort the multiple items 63 of the shared content in chronological order such as year, month, day, day of the week, etc. If the category of vote in favor or vote against is selected, the display device 11 can display only the items 63 of the shared content that have a priority or are higher than the value determined by the vote. As Figure 6 shown in

[0072] Referring again to Figure 7 the user 13 can navigate the shared content based on selecting an item 73 of the UI 71 for the shared content to be reproduced. For example, the user can slide the item 73 of the UI 71 in the up and down direction 78. The display device 11 can display the items 63 of multiple shared contents while focusing on the currently selected one or more items 65, as Figure 6As shown. For example, according to user 13 who selects corresponding item 65, the focus on each item 65 can be distinguished from each other by different colors. The display device 11 can move the focus to the item 65 of the selected shared content according to the sliding direction 78 of the user input of item 73 to the first user terminal 41.

[0073] Referring again to Figure 7 , user 13 can use item 74 of UI 71 to start reproducing the selected shared content. For example, user 13 checks whether the shared content of item 65 focused by the display device 11 is the content he / she expects to reproduce, and selects item 74 of UI 71, thereby starting to reproduce the corresponding shared content. Alternatively, user 13 can perform a press with a strength stronger than a predetermined level or drag left or right while sliding item 73 in the up and down direction 78, thereby starting to reproduce the corresponding shared content.

[0074] In response to the selection of item 74 of the first user terminal 41, the display device 11 can start reproducing the shared content of the currently focused item 65. According to an exemplary embodiment, the display device 11 can use the currently reproduced shared content as the wallpaper image of UI 61. For example, if the currently reproduced shared content is music, the wallpaper image of UI 61 can include the album cover of the music or an image related to the music extracted from an additional image received from an external server or the like.

[0075] The display device 11 can receive the data of the shared content to be reproduced from the first user terminal 41 of user 13 who requests reproduction, and reproduce the corresponding shared content based on the received data. There is no limitation on the method of transmitting the data of the shared content to be reproduced between the display device 11 and the first user terminal 41, but the data can be transmitted by a download method or a streaming method. Alternatively, the display device 11 can receive the data of the shared content to be reproduced from one or more content storage devices or units 14 other than the first user terminal 41 of user 13 who requests reproduction. The content storage device 14 can include, for example, a personal computer (PC), a smart phone, a smart tablet computer, a universal serial bus (USB) memory, a server, etc., as Figure 1 shown. Referring to Figure 2 , the display device 11 can receive the data of the shared content to be reproduced from the content storage device 14 through the first communicator 23, or can also include a second communicator 27 (see Figure 2 ) that uses a communication method different from that of the first communicator 23 so as to receive the data of the shared content to be reproduced from the content storage device 14 through the second communicator 27. The second communicator 27 can include at least one of a communication device, an interface, and a transceiver.

[0076] According to an exemplary embodiment, the first user terminal 41 provides a UI for searching for shared content and sends information related to a search query input through the UI to the display device 11. The display device 11 may search for shared content from the content storage device 14 based on the information related to the query for searching for shared content received from the first user terminal 41 and provide the user 13 with the result of the search for shared content.

[0077] The display device 11 may perform data processing for reproducing the shared content. The data processing for reproducing the shared content may be implemented corresponding to the format or attributes of the content. The display device 11 may output the result of processing the data of the shared content to be reproduced. For example, the display device 11 may output an audio signal of the shared content to be reproduced, or display a moving image or a still image of the shared content to be reproduced. To implement such an operation, the display device 11 may further include at least one of an audio processor for processing audio data and a speaker for outputting an audio signal. As another example, the display device 11 may send the result of processing the data of the shared content to be reproduced to an external device.

[0078] Referring again to Figure 7 , while reproducing the shared content, the user 13 may select an item 75 of the UI 71 and jump to the next shared content. In response to the selection of the item 75 in the first user terminal 41, the display device 11 starts reproducing the shared content of the item 63 next to the currently focused item 65.

[0079] The user 13 may select Figure 7 the item 76 of the UI 71 shown in

[0080] to increase the preference for the desired shared content. In response to the selection of the item 76 in the first user terminal 41, the display device 11 increases the preference for the shared content specified by the user 13. The display device 11 stores a value corresponding to the preference for each shared content in the storage device 26 and changes the value corresponding to the preference for the shared content stored in the storage device 26 as the user 13 develops a preference for the shared content. According to the selection of the user 13, the preference or rating for the shared content may be decreased. Figure 7 The user 13 may control the volume of the shared content being reproduced by selecting the item 77 of the UI 71 shown in

[0081] The display device 11 can display the reproduction control state of each user 13 according to the shared content being reproduced. For example, the display device 11 can display a visual effect with the following visual effect: a visual effect that instantaneously changes depending on the state in which each user 13 manipulates the user terminals 41, 42 to control the reproduction of the shared content. The display device 11 can distinguish the visual effects having this visual effect among the users 13.

[0082] Figure 9 Is Figure 6 An enlarged view of the area "A" in the UI 61 shown in. As Figure 9 shown, the display device 11 can display the grid 91 having a lattice pattern assigned to the user 13 of the shared content as this visual effect or visual effect. For example, each grid 91 can be distinguished according to the color of the user 13.

[0083] The display device 11 receives information related to the user control state for controlling the reproduction of the shared content from each of the user terminals 41 and 42. For example, the user control state for reproducing the shared content can include the movement or tilt of each of the user terminals 41 and 42. As Figure 9 shown, if the user 13 tilts the first user terminal 41 in the left direction 92 to control the reproduction of the shared content, the first user terminal 41 sends information related to the tilt direction 92 to the display device 11. The display device 11 can display the grid 91 corresponding to the first user terminal 41 as being transformed in the direction 93 corresponding to the tilt direction 92 of the first user terminal 41 based on the information received from the first user terminal 41. Therefore, each user 13 can interact with the screen of the display device 11 while viewing the visual effect that instantaneously reflects the control state of his / her control of the reproduction of the shared content, thereby obtaining a more interesting shared content experience. The visual effects described in the exemplary embodiments are merely examples in the method of displaying the reproduction control state of each user 13 for the shared content to be distinguished according to the user. In other words, the inventive concept is not limited to this visual effect.

[0084] Figure 10 Shows another example of the UI displayed on the user terminal 12 according to an exemplary embodiment. Figures 11 to 19 Is another example of the UI displayed on the display device 11 according to an exemplary embodiment. Regarding Figures 10 to 19 the display device 11 and the user terminal 12 shown in according to an exemplary embodiment, descriptions related to elements that are the same as or similar to the elements of the display device 11 and the user terminal 12 described with reference to Figures 1 to 9 will be omitted.

[0085] As Figure 10As shown, the first user terminal 41 may display a UI 101 for controlling the reproduction of shared content. In an exemplary embodiment, the reproduction of shared content involves various situations that allow the user 13 to use the shared content through the display device 11. For example, the reproduction of shared content may include reproducing a moving image, displaying a photo, playing music, providing relevant information related to the content, etc. through the display device 11.

[0086] According to an exemplary embodiment, the UI 101 may include a cursor 102 and items 104 and 105 for selecting a category of shared content or sorting and / or arranging the items of shared content. The user 13 manipulates the cursor 102 shown in the UI 101 of the first user terminal 41 and moves the first user terminal 41, thereby controlling the reproduction of the shared content displayed on the display device 11. The first user terminal 41 sends information related to the movement of the cursor 102 and the first user terminal 41 to the display device 11, and the display device 11 performs an operation related to controlling the reproduction of the content based on the information received from the first user terminal 41.

[0087] As Figure 11 shown, the display device 11 may display a UI 111 for controlling the reproduction of shared content. The UI 111 displayed on the display device 11 may include a cursor 112 and an item 113 showing the shared content. The cursor 112 is displayed corresponding to the first user terminal 41 and the second user terminal 42, respectively. The cursor 112 may be distinguished by the colors respectively assigned to the user 13. The cursor 112 displayed on the display device 11 may be shaped to correspond to the cursor 102 displayed on the UI 101 of the first user terminal 41 and the second user terminal 42.

[0088] The item 113 showing the shared content may include at least one of a thumbnail image, a name, and a description of the content. There is no limitation on the pattern in which the items 113 showing multiple shared contents are arranged. In an exemplary embodiment, the items 113 may be randomly arranged. Alternatively, according to an exemplary embodiment, the items 113 showing the shared content may be arranged in various patterns, such as a 3D spherical pattern, etc.

[0089] Each item 113 showing the shared content may be displayed as if it is falling from the top of the UI 101 (reference numeral 114). The displayed item 115 may be animated to move as if it is sinking underwater (reference numeral 116). The size of the item 113 showing the shared content may be determined based on the number of shared contents to be displayed.

[0090] Figure 12 Shown is Figure 11 compared with the content displayed on the UI 111 shown inFigure 12 As shown, item 122 corresponding to the shared content displayed on UI 121 may be smaller than item 113 of the shared content displayed on UI 111 shown in Figure 11 . In addition, the display device 11 may display an image on the wallpapers of UI 111 and UI 121, and may enlarge or reduce the wallpaper image according to the dimensional changes of items 113 and 122 of the shared content.

[0091] Referring again to Figure 10 , user 13 may move cursor 112 displayed on display device 11 by controlling the movement of first user terminal 41. For example, if user 13 tilts first user terminal 41 in the up, down, left, and right directions 103, display device 11 may display that cursor 112 corresponding to first user terminal 41 moves in a direction corresponding to the tilt direction 103 of first user terminal 41. There is no limitation on the method of moving cursor 112 of display device 11 by manipulating first user terminal 41, and various methods are possible.

[0092] According to an exemplary embodiment, user 13 applies movement control to first user terminal 41 so that items 113 of the shared content may be arranged differently on display device 11. For example, user 13 may slide cursor 102 of first user terminal 41, or perform movement control of tilting first user terminal 41 in the up, down, left, and down directions 103 while cursor 102 is touched and held. In this regard, display device 11 may display all items 113 corresponding to multiple pieces of shared content arranged as shown in Figure 11 or Figure 12 to move up, down, left, and right, rotate in the horizontal or vertical direction, and enlarge or reduce. Therefore, user 13 arranges items 113 of the content in various patterns and more easily selects the desired shared content.

[0093] User 13 may specify item 113 of the shared content displayed on display device 11, thereby selecting the desired shared content to be reproduced. User 13 designates item 113 of the desired shared content with cursor 112 and starts reproducing the shared content. User 13 may use cursor 112 to select and focus on item 113 of the shared content, release the selection, or scroll. Cursor 112 may be displayed in the color of user 13 assigned to currently control cursor 112. Cursor 112 may repeatedly grow larger and smaller as if it is breathing, thereby arousing the interest of the user.

[0094] Figure 13 and Figure 14 show in Figure 11 and Figure 12Details of item 113 of certain shared content displayed on the shown UIs 111 and 112. As Figure 13 shown, before item 113 of the shared content is specified by cursor 112, item 113 of the shared content is shown as having the basic form described with reference to Figure 11 and Figure 12 . Specifically, item 113 of the shared content can be marked with an identifier 133 for indicating which user 13 the corresponding shared content belongs to. The color of identifier 133 can be the same as the color of the user 13 assigned to the corresponding shared content. Item 113 of the shared content can display a thumbnail image 134 of the corresponding shared content. Item 113 of the shared content can display information 135 related to the source of the corresponding shared content (i.e., the source that provides the corresponding shared content). According to an exemplary embodiment, when the source is the first user terminal 41, the source information 135 of the shared content may not be displayed, but the source information 135 of the shared content is displayed only when the source is, for example, a web page, an external device, or a similar content storage device 14 (see Figure 1 ).

[0095] Next, when item 113 is specified by cursor 112, item 113 of the shared content can be highlighted to indicate that focus is on item 113 (see 137 in Figure 13 ). The highlight 137 can be shown as surrounding the edge of item 113 and can be shaped, for example, as a rectangle. The highlight 137 can have the same color as the identifier 133 of the corresponding shared content. When focusing on item 113 of the shared content, additional information 138 of the shared content can be displayed. The additional information 138 of the shared content can include the title and description of the corresponding shared content, information provided by a specific service when connected to a specific service, etc. For example, the information provided by the specific service can be given in the form of the number of stars, and the number of stars indicates the level of recommended content, as shown in Figure 13 .

[0096] Next, in a state where item 113 of the shared content is in focus, user 13 can select item 113 so that the shared content can be reproduced. Referring to Figure 10 , user 13 can manipulate cursor 102 of the first user terminal 41 to select item 113 of the display device 11.

[0097] As Figure 13 shown, when item 113 of the shared content is selected by the input of user 13, the display device 11 can display that the cursor 112 on item 113 becomes smaller, as if it is grasping item 113 like the hand of user 13. Therefore, user 13 can select the shared content more interestingly because the shape of cursor 112 changes depending on his / her manipulation.

[0098] Figure 15 An example of the UI 141 displayed on the display device 11 according to an exemplary embodiment is shown. If an item 113 for sharing content is selected in response to an input from the user 13, the display device 11 reproduces the shared content 142 corresponding to the selected item 113. Figure 15 An example of displaying information provided on the network as a type of reproducing shared content 142 is shown. However, there is no limitation on the type of reproduced shared content. According to an exemplary embodiment, if the shared content is a moving image, the moving image can be reproduced. If the shared content is a still image, the still image can be displayed. Similarly, the shared content can be reproduced differently according to the type and format of the shared content.

[0099] According to an exemplary embodiment, the display device 11 can arrange and display the items 113 of the shared content differently.

[0100] Figure 16 and Figure 17 Examples of the UI 151 and UI 161 displayed on the display device 11 according to an exemplary embodiment are shown. As Figure 16 and Figure 17 shown, the items 113 of the shared content are arranged in the form of a two-dimensional grid or matrix in the UI 151 and UI 161. The display device 11 can display the UI 151 and UI 161 in response to an input from the user 14 to the first user terminal 41. In response to an input from the user 14 to the first user terminal 41, the display device 11 can Figure 11 and Figure 12 switch between the arrangements of the items 113 corresponding to the shared content shown in Figure 16 and Figure 17 shown. Therefore, since the items 113 of the shared content are arranged differently, the user 13 can more conveniently select the desired shared content.

[0101] As Figure 17 shown, if the cursor 112 reaches the edge of the screen, for example, the left edge, in response to an input from the user 14 to the first user terminal 41, the display device 11 scrolls all the items 113 (reference numeral 164) of the currently displayed shared content to the right so that one or more items 165 of the shared content that have not been displayed can enter the screen. As a non-limiting exemplary embodiment, if cursors 112 corresponding to multiple users 13 are displayed, the display device 11 can allow the items 113 of the shared content to be movable only when the cursors 112 corresponding to all the multiple users 13 reach the edge. Therefore, any of the multiple users 13 can have sufficient opportunities to view the items 113 of the shared content, and thus the convenience of the user can be improved.

[0102] According to an exemplary embodiment, the display device 11 may sort and / or arrange items 113 of shared content according to categories.

[0103] Figure 18 An example of the UI 171 displayed on the display device 11 according to an exemplary embodiment is shown. As Figure 18 shown, one or more items 113 of shared content are sorted and / or arranged according to categories in the UI 171. The UI 171 may display corresponding names 173 of the categories. In the UI 171, the categories are arranged horizontally, and the items 113 of shared content belonging to each category are arranged vertically. The sorting and / or arranging method is not limited to Figure 17 the example shown, and may vary differently.

[0104] Referring again to Figure 10 , the user 13 may use items 104 and 105 of the first user terminal 41 to select a category of shared content to be sorted and / or arranged. The selectable categories of shared content may include, for example, photos, moving images, music, web page information, etc. as types of content, or users, styles, preferences, time, etc. as methods of sorting content. There is no limitation on the selectable categories, and the selectable categories may include any category for sorting or arranging shared content. The first user terminal 41 sends information related to the category of shared content selected by the user 13 to the display device 11. The display device 11 displays the items 113 of shared content corresponding to the category selected by the user 13 sorted and / or arranged based on the information received from the first user terminal 41. Accordingly, the user 13 may more easily select shared content as needed because the items 113 of shared content are sorted and / or arranged differently.

[0105] According to an exemplary embodiment, the display device 11 may display the items 113 of shared content arranged at specific positions on the wallpaper image.

[0106] Figure 19 An example of the UI 181 displayed on the display device 11 according to an exemplary embodiment is shown. As Figure 19As shown, the UI 181 may include a wallpaper image 182 and one or more items 113 of shared content arranged on the wallpaper image 182. In an exemplary embodiment, the wallpaper image 182 may be a map image, but is not limited thereto. Each item 113 of shared content is displayed at a specific location 184 that matches the shared content on the map image (i.e., the wallpaper image 182). For example, if the shared content is information related to a restaurant, the corresponding item 113 may be displayed at the location 184 corresponding to a specific point on the map 182 where the restaurant is located. The user 13 manipulates the first user terminal 41 to move the map (i.e., the wallpaper image 182) up, down, left, and right, or to zoom in or out of the map, thereby searching for the items 113 of shared content as needed. Accordingly, the user 13 can more conveniently select the shared content as needed.

[0107] According to an exemplary embodiment, the display device 11 may provide a function of searching for shared content.

[0108] Figure 20 An example of the UI 191 displayed on the display device 11 according to an exemplary embodiment is shown. As Figure 20 shown, the UI 191 may include items 192 and 193 of shared content and a search box 194. In response to an input from the user to the first user terminal 41, the display device 11 may display a search term 195 corresponding to the shared content that the user 13 desires to search for, such as the country "Korea", in the search box 194. The display device 11 searches for the shared content corresponding to the fully entered search term 195 and displays the searched items 192 of shared content in the UI 191. The display device 11 may display the searched items 192 of shared content more prominently than another item 193 of shared content displayed before the search, so that the user 13 can easily identify the search results. For example, the searched items 192 of shared content may be arranged in the front, while another item 193 of shared content may be arranged in the back. The searched items 192 of shared content may be enabled, but another item 193 of shared content may be disabled. The disabled another item 193 of shared content may be displayed more faintly or more darkly.

[0109] The user 13 may start the search function for the shared content through the first user terminal 41 and input a search term for the shared content that the user desires to search for. Referring again to Figure 10, according to an exemplary embodiment, the user 13 may use the item 105 of the first user terminal 41 to start the search function, but is not limited thereto. When the search function is started, the first user terminal 41 displays a UI for inputting a search term on the screen of the first user terminal 41 so that the user 13 can input the search term. According to an exemplary embodiment, the first user terminal 41 may receive the search term based on the voice input of the user 13 via, for example, a microphone provided in the user terminal.

[0110] Referring again to Figure 20 , the display device 11 may display the search box 194 in the same color as the color assigned to the user 13 currently using the search function, and thus it is easy to know who is using the search function. If a specific user 13 starts the search function, the display device 11 pauses the cursor control corresponding to the specific user 13 and displays the search box 194. When a specific user 13 is using the search function, the display device 11 may prevent another user 13 from using the search function. The search function assigned to a specific user 13 may be valid until the corresponding user 13 inputs the termination of the search function or until a predetermined time has elapsed.

[0111] When the search function assigned to a specific user 13 terminates, the display device 11 releases the display of the search box 194 and resumes the cursor control corresponding to the user 13. Therefore, it is more convenient for the user 13 to select the desired shared content through the search function for the shared content.

[0112] According to an exemplary embodiment, if a specific user 13 requests to reproduce the shared content, the display device 11 may start reproducing the requested shared content after a predetermined standby time has elapsed from the request time point. Therefore, another user 13 may have an opportunity to select the shared content according to her needs during the standby time. The standby time may be applied separately to each piece of shared content and is independently timed starting from the time when a request to reproduce each piece of shared content is made.

[0113] Referring to Figure 14 , the display device 11 may display a timer 1392 for showing the standby time on the item 113 of the shared content requested to be reproduced.

[0114] The display device 11 can reproduce only the shared content among the multiple pieces of shared content whose standby time ends first for which reproduction is requested. The display device 11 can reproduce the multiple pieces of shared content for which reproduction is requested in the order in which their standby times end. For one piece of shared content, multiple users 13 can make repeated requests. In this case, as the number of users 13 requesting reproduction increases, the standby time can become shorter or the standby time can elapse more quickly. In other words, the shared content requested by more users 13 can be reproduced preferentially. When multiple users 13 repeatedly request shared content more times, the display device 11 can enlarge the timer 1392, display the timer 1392 three-dimensionally, or give a similar visual effect. Therefore, according to the exemplary embodiment, the shared content desired by multiple users is preferentially reproduced by considering the preferences of multiple users.

[0115] Figure 21 And Figure 22 are other examples of the UI displayed on the display device 11 according to the exemplary embodiment. Regarding Figure 21 and Figure 22 shown in the display device 11 and the user terminal 12, descriptions related to elements that are the same as or similar to the elements of the display device 11 and the user terminal 12 shown in Figures 1 to 20 will be omitted.

[0116] Figure 21 The UI 201 shown in includes a cursor 112, one or more items 113 that display shared content, and an item 205 that indicates the user and / or preference. According to the exemplary embodiment, Figure 21 The shared content shown in, for example, may be a photo, but is not limited thereto. For example, the items 113 corresponding to multiple photos can be arranged in a 2D grid or matrix. Each item 113 of the shared content additionally includes an item 205 for indicating the user and / or preference. The item 205 is displayed in the color assigned to each user 13, and thus it is notified which user terminal has shared the corresponding photo. The shape of the item 205 is similar to a bar so that the preference for the photo can be indicated by the length of the bar.

[0117] The display device 11 moves the cursor 112 in response to a user input received from the user terminal 12. The display device 11 focuses on the item 204 of the photo where the cursor 112 is currently located. For example, the item 204 of the currently focused photo can be displayed as larger than the other items 113 and can be tilted at a predetermined angle. According to the exemplary embodiment, referring again to Figure 10, when the item 204 of the photo is displayed on the display device 11, if the user 13 touches the UI 101, the first user terminal 41 can make the cursor 102 larger. In this case, the display device 11 can make the cursor 112 smaller. Therefore, the circle of the cursor 102 displayed on the first user terminal 41 is enlarged as if it is pressed, and the cursor 112 displayed on the display device 11 is reduced as if it is grasping the photo, thus giving the user a more interesting control experience. Alternatively, according to the intensity of the user 13 touching the UI 101, the cursor 102 displayed on the first user terminal 41 can be enlarged or reduced.

[0118] Reference Figure 22 , in response to the user input received from the user terminal 12, the display device 11 can display an editing area 212 at the lower end of the UI 211. The editing area 212 can display an item 213 for creating an album. If the user 13 selects the item 213 through the cursor 112, the display device 11 displays an item 215 of the album to be edited. Each user 13 can move one or more items 113 of the desired photo to the item 215 of the album by methods such as drag and drop. Therefore, multiple users 13 can create a shared photo album with their desired photos. The display device 11 can additionally display an item 217 to the item 215 of the album, thereby indicating the user of the photo included in the album. The item 217 is displayed in the color (or multiple colors) of the user 13 assigned to each photo included in the album, so it is easy to know whose photos the album includes. The shape of the item 217 can be similar to a strip including a color bar, and if the album includes photos corresponding to multiple users 13, the length of each color bar can be proportional to the number of photos of each user 13 included in the album. Therefore, it is easy to know the information related to the user who created the album.

[0119] Figure 23 is another example of the UI displayed on the user terminal according to an exemplary embodiment.
